A Coding Theorem for f-Separable Distortion Measures [PDF]
In this work we relax the usual separability assumption made in rate-distortion literature and propose f -separable distortion measures, which are well suited to model non-linear penalties.

The Distortion Theorem for quasiconformal mappings, Schottky’s Theorem and holomorphic motions [PDF]
We prove the equivalence of Schottky’s theorem and the distortion theorem for planar quasiconformal mappings via the theory of holomorphic motions. The ideas lead to new methods in the study of distortion theorems for quasiconformal mappings and a new proof of Teichmüller’s distortion theorem.

A distortion theorem for quasiconformal mappings [PDF]
There exists a constant \(C=C(K,n)\) such that for any K-quasiconformal mapping \(f: B^ n\to {\mathbb{R}}^ n\) and for any \(z\in B\) there exists \(x\in \partial B^ n\) with \(| z-x| 1) \] where \(f^*\) is the nontangential maximal function.

A distortion theorem for analytic functions [PDF]
Let f ( z ) f(z) be a function analytic in the disk E { z : | z | > 1 } E\{ z:|z| > 1\} and for some real number n > 0 n > 0 let

A rate-distortion theorem for arbitrary discrete sources [PDF]
Summary: A rate-distortion theorem for arbitrary (not necessarily stationary or ergodic) discrete-time finite-alphabet sources is given. This result, which provides the expression of the minimum \(\varepsilon\)-achievable fixed-length coding rate subject to a fidelity criterion, extends a recent data compression theorem by [\textit{Y.

ON MULTIVALENT HARMONIC MEROMORPHIC FUNCTIONS INVOLVING HYPERGEOMETRIC FUNCTIONS [PDF]

Distortion theorems for Bloch functions [PDF]
We establish various distortion theorems for both normalized locally schlicht Bloch functions and normalized Bloch function with branch points. These distortion theorems give lower bounds on either
